1. Two chiral centres ( diastereoisomers ). Mirror O O. S R Two enantiomers N. OH HO. N differ by absolute configuration HN NH2 NH2 NH. A molecule with 1 stereogenic centre exists as 2 stereoisomers or enantiomers Enantiomers have identical physical properties in an achiral environment A molecule with 2 stereogenic centres can exist as 4 stereoisomers Enantiomers (mirror images) still have identical physical properties diastereoisomers (non-mirror images) have different properties O2N O2N.
